Description

Technical Field

[0001] This utility model belongs to the field of trademark tape drying devices, and particularly relates to an ultra-soft and thin trademark tape drying device. Background Technology

[0002] The characteristics of ultra-soft and lightweight label tape are that it usually uses high-count cotton yarn, polyester yarn, nylon yarn, rayon, etc. as warp and weft threads. These materials are soft and lightweight, with a thickness of less than 0.3mm and a weight of less than 50 grams per square meter.

[0003] The production process of label tape includes washing and drying steps. One end of the label tape is continuously pulled through a drying device, absorbing heat from the device to evaporate moisture. In actual production, it has been found that ultra-soft and thin label tapes have particularly high requirements for drying time and temperature. When the drying device fluctuates around the set temperature, or when the label tape's movement speed fluctuates, causing fluctuations in the set drying time, the dried label tape is prone to curling and unevenness. This is especially noticeable with label tapes made of polyester and nylon fibers, making production control extremely inconvenient. This control refers to adjusting the drying temperature and the label tape's movement speed. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-soft and lightweight label drying device.

[0005] This invention has the advantage of being relatively convenient for production control.

[0006] The technical solution of this utility model is as follows: an ultra-soft and thin trademark strip drying device, including an insulated box, an inlet on one side of the upper part of the insulated box, an outlet on the other side of the upper part of the insulated box, a heater inside the insulated box, a perforated pressure plate on the top surface of the heater, the inlet, the outlet and the pressure plate are on the same plane, and two heat dissipation plates are provided at the outlet. The trademark strip passes through the inlet, between the heater and the pressure plate, and between the outlet and the two heat dissipation plates in sequence.

[0007] In the aforementioned ultra-soft and thin trademark strip drying device, the heater includes a heating box, a heating unit with adjustable power is provided inside the heating box, and a heat storage plate fixed to the heating box is provided above the heating unit.

[0008] In the aforementioned ultra-soft and lightweight trademark strip drying device, a digital display thermometer is provided on the outside of the heat preservation box, and the detection end of the digital display thermometer is located in the heat storage plate.

[0009] In the aforementioned ultra-soft and thin trademark strip drying device, the top of the heating box is provided with multiple first positioning pins that pass through the pressure plate.

[0010] In the aforementioned ultra-soft and thin trademark strip drying device, the heating box is equipped with an air pressure balance hole.

[0011] In the aforementioned ultra-soft and lightweight trademark strip drying device, the heat dissipation plate is provided with multiple heat dissipation fins, and the lower heat dissipation plate is provided with a second positioning pin that passes through the upper heat dissipation plate.

[0012] In the aforementioned ultra-soft and lightweight trademark strip drying device, the outer periphery of the heat preservation box, the outer periphery of the heating box, and the bottom surface of the heating box are all covered with heat insulation material.

[0013] In the aforementioned ultra-soft and thin trademark strip drying device, a fan is provided on one side of the heat dissipation plate.

[0014] Compared with existing technologies, this invention utilizes a heater to dry the label strip. A perforated pressure plate on the heater presses the label strip against the heater for drying, preventing curling during the drying process. After the label strip is removed from the heat-insulating chamber, a radiator cools it down. During cooling, the label strip remains flat due to the combined action of the two radiators. The cooled label strip is close to the workshop air temperature, with a small temperature difference, preventing curling caused by temperature variations. Because the label strip is constantly under pressure during drying and cooling, it remains flat even with fluctuations in drying temperature and time, making production control more convenient. Therefore, this invention has the advantage of convenient production control.

[0015] By installing an insulated box through which the trademark tape passes on the outside of the heater, the heater is placed in a relatively stable temperature environment, reducing the impact of external temperature fluctuations on the heater. This results in smaller temperature fluctuations in the heater and also contributes to energy conservation.

[0016] By setting a first positioning pin through the pressure plate on the heating box, the distance between the pressure plate and the heating box can be automatically adjusted according to the thickness of the trademark strip. By setting a second positioning pin through the upper heat dissipation plate on the lower heat dissipation plate, the distance between the two heat dissipation plates can be automatically adjusted according to the thickness of the trademark strip. This invention can dry trademark strips of different thicknesses and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example: A drying device for ultra-soft and thin label strips, such as... Figure 1 As shown, it includes an iron insulated box 1, with a feed inlet 2 on one side of the upper part of the insulated box 1 and a discharge outlet 3 on the other side of the upper part of the insulated box 1.

[0023] The insulation box 1 is equipped with a heater, which includes a stainless steel heating chamber 6. The heating chamber 6 has a pressure balancing hole 11 to reduce deformation of the heating chamber 6 due to thermal expansion and contraction. The heating chamber 6 contains an adjustable-power heating unit 7, which uses an infrared heating lamp. Above the heating unit 7 is a heat storage plate 8 fixed to the heating chamber 6, made of aluminum. A digital thermometer 9 is located on the outside of the insulation box 1, with its sensing end located within the heat storage plate 8.

[0024] The top surface of the heating chamber 6 is provided with a perforated pressure plate 4, which is made of stainless steel. The holes on the pressure plate 4 are used to discharge water vapor. The top surface of the heating chamber 6 is provided with multiple first positioning pins 10 that pass through the pressure plate 4, and the first positioning pins 10 are clearance-fitted with the pressure plate 4. The feed inlet 2, the discharge outlet 3 and the pressure plate 4 are on the same plane.

[0025] Two aluminum heat sinks 5 are provided at the discharge port 3. The label strip 16 passes sequentially through the feed port 2, between the heater and the pressure plate 4, and between the discharge port 3 and the two heat sinks 5. Multiple heat sink fins 12 are provided on the outer side of the heat sink 5. A second positioning pin 13 passes through the upper heat sink 5 on the lower heat sink 5. The second positioning pin 13 is clearance-fitted with the upper heat sink 5. The lower heat sink 5 is fixed to the heating box 6. A fan 15 is provided on one side of the heat sink 5. The fan 15 can be fixed to the ground by a bracket or fixed to the heating box 6 by a bracket.

[0026] The outer periphery of the insulated box 1, the outer periphery of the heating box 6, and the bottom of the heating box 6 are all covered with heat insulation material 14 to reduce heat loss.

[0027] Working principle: Based on the temperature value displayed on the digital thermometer, the power of the heating unit 7 is adjusted accordingly to maintain the heat storage plate 8 at the set temperature, which is maintained between 130-160℃. A smaller range can be selected depending on the specific material; for example, 140-145℃ can be used for polyester filament. The heat storage plate 8 absorbs a large amount of heat from the heating unit 7, with minimal temperature fluctuations, and transfers the heat to the top plate of the heating chamber 6.

[0028] The label strip passes through the top of the heating box and is dried by evaporating moisture. The evaporated moisture leaves the label strip through the holes on the pressure plate 4. During the drying process, the label strip is kept flat by the weight of the pressure plate 4. The pressure plate 4 is restricted by the first positioning pin 10 and will not slide under the friction of the label strip.

[0029] After the label tape is dried, it enters between the two heat sinks 5. The heat it carries is absorbed by the heat sinks 5, causing it to cool down rapidly and set its shape, making it less prone to curling again. The heat from the heat sinks 5 is released into the air through the heat sink 12, and the fan 15 accelerates this process, keeping the heat sinks 5 at a low temperature (below 40°C). In hot weather, if the heat sinks 5 cannot maintain a low temperature, a humidifier can be installed on the air intake or exhaust side of the fan 15 to increase the humidity of the airflow, which can significantly reduce the temperature of the heat sinks 5.

[0030] Since both the pressure plate 4 and the upper heat dissipation plate 5 can be raised and lowered freely, this utility model is suitable for drying trademark strips of different thicknesses and has a wide range of applications.

[0031] With further improvements, the top plate of the heating box 6 can be set in a herringbone shape or tilted, and a sponge can be attached. When the water vapor rises, the sponge can absorb the water droplets condensed from the water vapor. The water droplets slide outwards and drip down under gravity, instead of dripping back onto the pressure plate 4.

[0032] The heat sink 5 can also be surface hardened, such as anodizing, nickel plating, or ion implantation, to slow down the wear rate of the heat sink 5 and reduce the replacement frequency.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
